A bifunctional nanozyme with dual oxidase- and catalase-mimicking activities for catalytic oxidation cycling of its target substrate

As a bifunctional nanozyme, it can convert O 2 to H 2 O 2 via its oxidase-mimicking activity, and then regenerate O 2 from H 2 O 2 via its own catalase-mimicking activity, enabling catalytic oxidation cycling of its target substrate.
